Automatic validation and JSON round trip from TypeScript types
interface User {  id: number;  name: string;  createdAt: Date;  tags: Set<string>;}
A plain function is a route; its params arrive fully validated
const routes = {  getUser: mion.query((ctx, id: number): User | null => {    if (id !== 1234) return null;    return {      id: 1234,      name: 'John',      createdAt: new Date(),      tags: new Set(['admin']),    };  }),  // ...other routes} satisfies Routes;export const myApi = mion.initRoutes(routes);export type MyApi = typeof myApi;startNodeServer({port: 3000});

// packages/private-examples/src/_homepage/home-rpc-client.tsimport {initClient} from '@mionjs/client';import type {MyApi} from './home-rpc-server.ts';const {routes} = initClient<MyApi>({  baseURL: 'http://localhost:3000',});
Remote routes are called like local async functions, fully typed
const [user, error] = await routes.
getUsergetUser(1234).call();if (user) {  user.
User.createdAt: DatecreatedAt;  // @annotate: Native classes like Set come back as real values  user.
User.tags: Set<string>tags;}// Type error: id must be a number// @ts-expect-error -- shown on purpose; the assertion fails the build if this ever stops erroringroutes.getUser('1234').call();
